A Far-Ultraviolet Study of the Old Nova V841 Ophiuchi
Sion, Edward M.; Engle, Scott G.
We have carried out a synthetic spectral analysis of archival International Ultraviolet Explorer spectra of the old nova V841 Oph (Nova Oph 1848) taken 15 years apart. The spectra reveal a rising continuum shortward of 1560 Å, a C IV P Cygni profile indicative of wind outflow associated with disk accretion in one spectrum, a deep Lyα profile, and …
uvby FCAPT Photometry of the Magnetic Chemically Peculiar Stars 36 Aurigae, HR 2722, 13 Andromedae, and HD 220147
Adelman, Saul J.
Differential Strömgren uvby observations obtained with the Four College Automated Photoelectric Telescope (FCAPT) are presented for the magnetic chemically peculiar (mCP) stars 36 Aur, HR 2722, 13 And, and HD 220147. The new data help to better define the light curves. The period for 36 Aur was found to be 14.368 days, close to that for the previo…
Looking for Discrete UV Absorption Features in the Early-Type Eclipsing Binaries µ1 Scorpii and AO Cassiopeiae
Sahade, J.; Kondo, Y.; Arias, M. L. +1 more
A search for discrete absorption components in the ultraviolet spectra of the early-type binaries µ1 Scorpii and AO Cassiopeiae has been undertaken by analyzing material secured with the International Ultraviolet Explorer satellite during an exclusively assigned interval of nearly 50 hr. While the spectra of µ1 Sc…
